What your xSeries 350 offers
The design of your server takes advantage of advancements in symmetric
multiprocessing (SMP), data storage, disk-array technologies, and memory
management. Your server combines:
• Impressive performance using an innovative approach to SMP
Your server supports up to four Pentium III Xeon microprocessors. Your server
comes with at least one microprocessor installed; you can install additional
processors to enhance performance and provide SMP capability.
• Large data-storage and hot-swap capabilities
The xSeries 350 server supports up to three standard and three optional 26 mm (1-
inch) slim-high 3.5-inch hot-swap hard disk drives in the hot-swap bays. This hot-
swap feature enables you to remove and replace hard disk drives without turning
off the server.
• Active PCI
™
(hot-plug) adapter capabilities
Your server has six hot-plug slots for PCI adapters. With operating system
support, you can replace failing hot-plug PCI adapters without turning off the
server. If the hot-add feature is supported by your operating system and the PCI
adapter, you can also add PCI adapters in these slots without turning off the
server.
• Redundant cooling and power capabilities
The redundant cooling and hot-swap capabilities of the fans in your server enable
continued operation if one of the fans fails. You can also replace a failing fan
without turning off the server.
The server comes with one 270-watt power supply. Install additional 270-watt
power supplies to ensure redundancy and hot-swap capability for a typical
configuration. (See “Chapter 5. Installing options,” on page 29 for instructions.)
